Looking for Year End Rounding Script

During our last year end closing we had a issue come up in which we found out that some journal entries had not been rounded to the hundredths place before being uploaded in GP. We had a round time finding all of the little areas in which need to be have fractions of penny changed. Does anyone out there have a script that could possible help us fix this issue? We know this is probably going to happen again and would like to make it a little easier on ourselves this year.
